What is DISC; what is DiSC®?
Have you seen DISC profiles for sale that seem different from each other? Is the difference more than a lowercase i? Yes. Is the Disc Index different from the DiSC Classic? Yes. It’s important to know which assessment is actually under discussion. They are not all the same. When you see claims that millions of people have used DISC, don’t assume that millions have used the version you might be discussing or considering buying.
The flavors of DISC
The DISC model is not protected by copyright. The DiSC Model of Behavior was first proposed by William Mouton Marston, a Ph.D. psychologist from Harvard. He did not create an assessment tool himself, but others have used his model. Several academics and companies have used his work to create their own psychological inventories.
Depending on the assessment author, DISC can be an acronym for:
- Dominance or Drive
- Influence or Inspire
- Steadiness, Stability or Submission
- Compliance, Correctness or Caution
Various colors might be used to differentiate each personality type.
How to choose among the DISC tests
Questions should be easily and accurately answered.
Here’s an example of a test item from a free DISC test:
For each group of four descriptions you should have one most like you and only one least like you.
○ My behavior is well disciplined
○ People see me as being generous
○ I am always on the move
○ I persevere until I get what I want
You can see how this would be hard to answer. Many DISC tests and DiSC Classic use this type of forced choice or ipsative questionnaire.
Other questionnaires will use a Likert scale where you rank each item on a five-point scale from “never” to “always“ describes me. Or the scale will show choices of “strongly disagree” to “strongly agree” with the statement. This type of question gets more useful answers.
Look at the number of questions being asked. A 70-item questionnaire is more reliable than a 20-item questionnaire. An adaptive testing tool which tailors questions on past answers is currently used by Everything DiSC profiles making them more accurate and even easier to answer.
You can’t do much with a report that gives you only a page or two about your results. The real power of DiSC is in both what it teaches you about yourself and what it teaches you about interacting with others who have styles unlike your own.
Reports should be easily read, memorable and accurate. They should take care with language, presenting all personalities in a balanced manner. Reports full of charts and graphs can be interesting, but they also need to be memorable and easy to interpret.
If you hear people criticize DISC profiles for lacking reliability or validity, they are almost always referring to issues around the presentation of an adaptive style. After multiple attempts, researchers at Inscape Publishing (now a part of Wiley) were not able to validate the adaptive style graphs; therefore, they were abandoned.
We recommend reading the full descriptions for the four styles with an eye toward the language being used. Would a C reading about her style feel like it was harsh and judgmental, or accurate and affirming? Would an S reading about his style feel like he was reading about a pushover or would it feel supportive and clear?
Wiley, the publisher of all of Everything DiSC assessments, is committed to maintaining the highest standards of instrument development and application through a careful research and development process. They ensure all of the instruments offer valid scores and accurate feedback to the respondent.
